Really beautiful.
I apologize for the horrible comparison photos, but it seems to resemble
Mastophora pacifica to me. Keep in mind these pictures were taken in the absence of actinic lighting which could explain the stronger colors in your specimen. It could also be another of the four species in the
Mastophora genus which aren't well documented.
